Rear Brakes and toys

[TGViper]

Ok - so I got my new Exhaust system today (MarkT - mild2wild) and am really itchin to put them on but have a couple questions. 

I just bought the bike last month and I KNOW I have to do the following:

1.  Front brakes - have parts ordered, be here next week.
2.  Rear brakes - same status
3.  Lube spline and replace "o" rings - same status.  Not sure this was done by previous owner and bike now has 37K.  I like to know what I got so it is probably a good time to do this.
4.  Change oil - was done last fall but not this spring yet.

My question is:   

1.  If I put the new exhaust on, will I need to take it off again for any of the items listed above? 

Thanks in advance,

Viper

It's not necessary to remove the exhaust to do any of those...so I'd say, "Go for it!"
